Can you identify the man-related activities that are contributing to the loss of biodiversity?

The main human activity that affect biodiversity are habitat destruction, foreigner species importation and hunting.

Habitats destruction is the main cause of loss of diversity. More that the destruction of specie's habitats, the patches that are still viable for species get isolated from one another wich lead to a decreas in genetique exchange (wich tend to consanguinity).

Through human activities, animals and vegetal species also have been introduce to new habitats all over the world. Those species when they manages to survive, they often thrive and exculde native species through competition or predation.

Lastly, hunting also had and still have a major impact on animal population. Several very known species get extinct through hunting.
